Filtrando todas aqellas que sean setosa

setosa <- filter(iris, Species == "setosa")
datatable(setosa)

Seleccionando Sepal.Lenght

largo_sepalo_setosa <- select(setosa, Sepal.Length)
datatable(largo_sepalo_setosa, extensions = 'Buttons', options = list(dom = 'Bfrtip', buttons = c('copy', 'csv', 'excel', 'pdf', 'print')))

Felicidades muy buen trabajo
